Investigation of Efficiency of Additional Determination Method of the Model Selection in the Modeling Problems by Application of GMDH Algorithm

摘要

The problem of optimal model selection often occurs in real problems of modeling because there can be several equally accurate models. For this case the method of model additional determination by additional bias criterion is proposed. At first the regularity criterion is calculated, then if it is impossible to select the optimal model, the additional bias criterion is calculated for the models that belong to the interval of uncertainty. The examples of model additional determination are shown in the selection problem of aircraft surface material.
